Prescription Lens Holder for Windows Mixed Reality Headsets

This is a work-in-progress lens holder to hold prescription lenses from the [Zenni Round Glasses](https://www.zennioptical.com/p/metal-alloy-full-rim-frame-with-spring-hinges/5500?skuId=550021) in a Windows Mixed Reality VR headset. Should work in all of the non-Samsung ones.

The basic measurements are correct and it works fine, but it needs some additional tweaks to lock it rotationally and also to make it a little bit easier to install. I will work on it some more as I have time. Suggest
